Struct Array

in my .c file i have a struct atop of the program defined as follows:
Code:
#define MAX 10
int curtab;

static struct tab {
	int count;
	int use;
} tab[MAX];

with the initial function following it like so:
Code:
int tab_create(int init_count)
{
       int i;
       for(i=0; i < MAX; i++)
	{
		if(tab[i].use != 1)
		{
			tab[i].use = 1; /* true */
			tab[i].count = init_count;
			curtab = i;
			i = MAX; /* break */
		}
	}
       return (curtab);
}

but I find I receive a Seg-Fault error at
Code:
if(tab[i].use != 1)

Why does this occur?

XmTabListCopy(library call)											       XmTabListCopy(library call)

NAME
XmTabListCopy -- A convenience function that creates a new tab list from an existing list SYNOPSIS
#include <Xm/Xm.h> XmTabList XmTabListCopy( XmTabList tablist, int offset, Cardinal count); DESCRIPTION
XmTabListCopy creates a new tab list consisting of a copy of a portion of the contents of the tablist argument. This function starts copy- ing at the specified offset value of the tab list and copies count values. tablist Specifies a tab list to be copied. offset Specifies where to start copying. A value of 0 (zero) indicates begin at the beginning, a value of 1 indicates to skip the first tab, and so on. A negative indicates to begin counting backwards from the end. A value of -1 indicates to start copying from the last tab. count Specifies the number of tabs to copy. A value of 0 (zero) indicates to copy all elements from the starting point to the end (beginning if offset is negative) of the tab list. RETURN
If tablist is NULL, this function returns NULL. Otherwise, this function returns a newly allocated XmTabList. If the function does allo- cate an XmTabList, then the application is responsible for managing the allocated space. The application can recover the allocated space by calling XmTabListFree. RELATED
